In the original publication of this article [1], “AN” is missing in the column heading “Patients underwent NS at the (n = 46)” in Table 1 due to a typesetting error. The correct column heading should be “Patients underwent NS at the AN (n = 46)”. Moreover, the asterisk symbol * in “27 (84)*” and “5 (45)*” should be removed.

In addition, the phrase “using FLOQBrushes (Copan Italia, Brescia, Italy)” needs be added in the first sentence under the header “OM sample collection” of the Methods section.

The first sentence should be changed to:

NS was performed by otolaryngologists in each unit, independently, using FLOQBrushes (Copan Italia, Brescia, Italy).

The original article [1] was updated.
